योग्य उत्तर 106 आहे.

  • सोडियम कार्बोनेट ( Na2CO3) चे चर्वणक वस्तुमान 106 आहे.

सोडियम कार्बोनेट ( Na2CO3) चे चर्वणक वस्तुमान खालीलप्रमाणे मोजले जाऊ शकते:

  • त्यात सोडियमचे दोन अणू, कार्बनचे एक अणू आणि ऑक्सिजनचे तीन अणू असतात.

आण्विक भारांक खालीलप्रमाणे मोजले जाऊ शकते:

Na : 2 x 23.0 =  46

C : 1 x 12.0 = 12

O : 3 x 16 = 48

  • वरील मूल्ये जोडणे म्हणजे 46 + 12 + 48 = 106
  • म्हणून, Na2CO3 चे चर्वणक वस्तुमान 106 ग्रॅम/मोल आहे.
